DETAILED DESCRIPTION OF EMBODIMENTS

[0028] In FIGS. 1 through 6, a device for pulling a hose and nozzle assembly is indicated generally by the reference numeral 10. The device 10 comprises a plate 12 defining a first laterally-extending aperture 14 forming a first laterally-extending grip, and a second laterally-extending aperture 16 forming a second laterally-extending grip. A lock 18 is spaced below the first and second grips 14 and 16, respectively, and is releasably engageable with the hose and/or nozzle of a hose and nozzle assembly 20. As shown typically in FIG. 6, the first laterally-extending grip 14 is manually engageable by a first hand, such as a left hand, to grip the device 10, and the second laterally-extending grip 16 is manually engageable by a second hand, such as a right hand, to grip the device, and pull the device while gripping it, including in a position behind the back, and thereby pull the hose and nozzle assembly 20 secured to the device. As shown typically in FIGS. 2-4, the lock 18 and/or hose and nozzle assembly 20 is movable relative to the other between (i) a locked position (e.g., FIGS. 2 and 3), wherein the hose and nozzle assembly 20 is secured by the lock 18 to the device and the hose and nozzle assembly is supported therefrom, and (ii) an unlocked position (e.g., FIG. 4), wherein the hose and nozzle assembly is released from the lock and detached from the device.

[0029] As shown typically in FIG. 1, the lock 18 is defined by a second aperture 22 spaced below the first and second laterally-extending apertures 14 and 16, respectively. The second aperture 22 defines a nozzle-engaging portion 24 and a nozzle-release portion 26. The nozzle-engaging portion 24 defines a first width or diameter 28 that is engageable with the nozzle to thereby support the nozzle on the device in the locked position. The nozzle-release portion 26 defines a second width or diameter 30 that is greater than the first width or diameter 28, and that allows the nozzle to pass through the nozzle release portion and thereby allow detachment of the hose and nozzle assembly 20 from the device. The nozzle-engaging portion 24 is located below the nozzle-release portion 26 to allow the mass of the hose and nozzle assembly 20 and gravitational force to retain the nozzle within the nozzle-engaging portion. The nozzle-engaging portion 24 and the nozzle-release portion 26 of the second aperture 22 are interconnected and allow manual movement of the nozzle between a locked position (e.g., FIGS. 2 and 3) engaging the nozzle-engaging portion, and a release position (e.g., FIG. 4) in the nozzle-release portion. In the illustrated embodiment, the nozzle-release portion 26 is approximately circular shaped, and the nozzle-engaging portion 24 is approximately partial elliptical shaped. Also in the illustrated embodiment, the nozzle-engaging portion 24 and the nozzle-release portion 26 define an approximate keyhole shape. However, as may be recognized by those of ordinary skill in the pertinent art based on the teachings herein, the illustrated shapes are exemplary and may be changed as desired or otherwise required.

[0030] As shown typically in FIG. 1, the first and second laterally-extending apertures 14 and 16 are approximately horizontally aligned and the second aperture 22 is spaced below the first and second laterally-extending apertures. A centerline 32 of the device is located between the first and second laterally-extending apertures 14 and 16. The second aperture 22 is approximately symmetrical about the centerline 32, and the first and second laterally-extending apertures 14 and 16 are approximately symmetrical about the centerline.

[0031] As shown typically in FIG. 1, the plate 12 is approximately triangular shaped. The first and second laterally-extending apertures 14 and 16 extend approximately parallel to a first leg or side 34 of the triangle. Also in the illustrated embodiment, the first and second laterally-extending apertures 14 and 16 extend from approximately one corner of the triangle to another corner of the triangle. The second aperture 22 of the lock defines an elongated axis that is coincident with the centerline 32 of the device, and is approximately perpendicular to the first leg or side 34 of the triangular plate. The first and second laterally-extending apertures 14 and 16 extend adjacent to the first leg or side 34 of the triangular plate 12, the second aperture 22 is spaced below the first and second laterally-extending apertures 14 and 16 and defines an elongated axis of symmetry that is coincident with the centerline 32 of the device, and the first and second laterally-extending apertures 14 and 16 are symmetrical about the elongated axis of symmetry. In the illustrated embodiment, the plate 10 preferably defines the shape of an isosceles triangle, and more preferably, the shape of a right isosceles triangle. However, as may be recognized by those of ordinary skill in the pertinent art based on the teachings herein, this shape is exemplary and may be changed as desired or otherwise required, including, for example, a square, rectangular, circular or elliptical shape.

[0032] As shown typically in FIG. 5, an exemplary nozzle body 36 defines an annular groove or recess 38, and the groove or recess defines a first width 40. As shown typically in FIG. 3, the nozzle-engaging portion 24 of the lock 18 defines a wall thickness 42 that is less than the first width 40 to allow the nozzle-engaging portion 24 to be received within the groove or recess 38 on the nozzle body and secure the nozzle thereto. In the illustrated embodiment, the wall thickness 42 of the nozzle-engaging portion 24 is approximately the same as the wall thick of the plate 12. In one embodiment, the first width 40 of the nozzle groove is about inch, and the wall thickness 42 of the plate is about 3/16 inch. In addition, the width 28 of the nozzle-engaging portion 24 is greater than the inner diameter of the groove 38 of the nozzle body, but less than the outer diameter of the groove 38, in order to allow the edge of the nozzle-engaging portion 24 to be received within the groove and thereby lock the nozzle body to the device.

[0033] As shown typically in FIG. 6, the device 10 may be used in accordance with the following steps: [0034] (i) moving the nozzle of a hose and nozzle assembly 20 into engagement with the lock 18 of the device 10, securing the nozzle to the lock 18, and supporting the hose and nozzle assembly 20 from the device; [0035] (ii) manually engaging one or both of the first and second laterally-extending grips 14 and 16 of the device; [0036] (iii) holding the device 10 in a position behind the back with the nozzle secured thereto and the hose and nozzle assembly 20 supported therefrom; and [0037] (iv) pulling the device 10 while held in the behind-the-back position and, in turn, pulling the hose and nozzle assembly 20 supported therefrom.

[0038] In the illustrated embodiment, the hose and nozzle assembly is a fuel oil hose and nozzle assembly, and step (iv) includes pulling the hose and nozzle assembly between a fuel truck and a heating oil tank, such as home or other heating oil tank. Also in the illustrated embodiment, step (ii) includes manually gripping with a left hand the left laterally-extending grip 14 of the device, and manually gripping with a right hand the right laterally-extending grip 16 of the device. When the hose and nozzle assembly is pulled to a tank, or pulled from a tank back to the truck, the procedural steps further comprise moving the nozzle of the hose and nozzle assembly 20 out of engagement with the lock 18 of the device and detaching the hose and nozzle assembly therefrom.

[0039] One advantage of the illustrated embodiment is that the hand grips 14, 16 and locking aperture 22 are symmetrical about the centerline 32 of the device, thereby providing symmetrical gripping surfaces to support the weight of the hose and nozzle assembly, and allowing ergonomic gripping and pulling of the hose and nozzle assembly while minimizing or reducing the risk of unnecessarily twisting the lower back while pulling the hose and nozzle assembly. As can be seen, the laterally-extending apertures 14, 16 and associated gripping surfaces allow users to comfortably grip the device at about the natural spacing of the hands when positioned behind the back. In the illustrated embodiment, each laterally-extending aperture defines a width extending parallel to the side 34 of the triangular plate within the range of about 4 to about 7 inches, and more preferably within the range of about 5 to about 6 inches. The web 44 extending between the laterally-extending grips defines a width extending parallel to the side 34 of the triangular plate within the range of about 0 to about 2 inches, preferably within the range about inch to about inch, and more preferably about inch. In the illustrated embodiment, the plate 12 is made of aluminum; however, as may be recognized by those of ordinary skill in the pertinent art based on the teachings herein, the device may be may of any of numerous different materials that are currently known or that later become known, including any of numerous different metals, plastics, composite materials, or combinations of any of the foregoing.

[0040] As may be recognized by those of ordinary skill in the pertinent art based on the teachings herein, numerous changes and modifications made be made to the above-described and other embodiments without departing from the scope of the invention as defined, for example, in the appended claims. For example, the shape and/or dimensions of the lock may take any of numerous different shapes and/or dimensions in order to releasably secure thereto any of numerous different hoses and/or nozzle assemblies that are currently known, or that later become known. In addition, the shapes and dimensions of the device and/or of the grips may be changed as desired or otherwise required. For example, the gripping surfaces could be expanded in thickness or width, the gripping surfaces could be changed to facilitate different or particular types of grips, and more or fewer apertures forming the grips could be provided. The peripheral shape need not be triangular, but rather may be defined any of numerous other shapes, such as rectangular, circular, oval or other shapes. The device need not be limited to pulling fuel oil hose and nozzle assemblies, but rather could be modified to secure and pull any of numerous different types of hoses, nozzles, conduits, lines and/or other hose and/or nozzle assemblies, such as firefighting hoses, that are currently known, or that later become known. In addition, the device could be covered or coated in whole or in part with any of numerous different coverings or coatings that are currently known or that later become known. For example, the plate and/or the gripping portions of the plate can be coated with a polymeric coating. The coating may increase the thickness of the device, including at the grips, to facilitate gripping the device. In one such embodiment, the coating may be up to about inch thick on each side of the device or plate 12. In addition, the coating could be colored, such as with a yellow or orange color, in order to allow the device to stand out against its background, particularly if it falls onto a snow-covered ground. If desired, a harness could be attached, such as by clips, to one or both laterally-extending grips, and/or to other aperture(s) formed on the device, and the harness could in turn be attached to a workman's belt, or otherwise secured to the workman, to pull the device and a nozzle and hose assembly secured thereto with the harness. Accordingly, this detailed description of embodiments is to be taken in an illustrative, as opposed to a limiting sense.
